' HAGERSTOWN, MARYLAND, A CORPORATION OF MARYLAND ORGAN VALVE Application filed March 17, 1931.

" ciated with a pipe organ or similar device.

Magnet valves of this type are usually formed as an integral unit adapted-to be attached to the outside of the action box with which they are associated. The valve elements in these units are extremely delicate '15 these valves inaction and frequently become clogged by particles of sawdust or other foreign matter carried into the action box by the air flowing therein. In many organ installations,

are placed in dark and inaccessible places about the organ structure, and when it becomes necessary to repair or adjust them for any reason, considerable difficulty has been experienced in properly replacing and adjusting the valve parts. It frequently happens that during assemblage or adjustment of these valves, the little disc armature valve element becomes disarranged relative to its valve seat and sometimes actually blows away before the parts are assembled and thus causes considerable annoyance and waste of time to the mechanic in making these repairs. I

The object of the present invention is to provide an improved electro-magnetic organ valve construction which shall facilitate the assemblage and operation of the valve parts and this object is accomplished by mounting all of the movable or adjustable valve parts on a removable closure element for the valve casing so that these parts may be removed from the valve casing as a unit without disturbing the adjustment or opera- 0 tive relation of the valve parts.

Another object of the invention is to provide a valve unit of the character designated having'a guide member for the movable valve element which shall also positively retain the same in the normal operative relation to its valve seat whenever the unit is removed from the casing for any reason.

A further object of the invention is to provide a magnet valve unit of the character designated which shall be durable in con- Serial No. 523,371.

struction and more eflicient in operation than similar valves heretofore employed.

These and other objects of the invention will be more manifest from the following description and drawing, and specifically set forth in the appended claims.

In the drawing:

Figure 1 is a sectional view of an organ wind box employing a magnet valve embodying my invention.

Figure 2 is a view in section of the valve element.

Figure 3 is a perspective view, showing the relation of the removable valve parts, and

Figure 4: is a top view of the valve casing.

Referring to Fig. 1 of the drawing, the numeral 10 indicates a wind or action box of a pipe organ employing a magnet valve constructed in accordance with my invention. This valve unit comprises a hollow metallic casing 11 and an electromagnet 12 having its pole pieces 13 mounted in the wall thereof which is attached to the organ act-ion box in a manner well understood in the art.

The interior of the casing 11 is arranged to form a valve chamber 1 1 and this chamber communicates with an outlet 15 by means of a conduit 16 also formed in the valve casing. The lower side of the casing is open and is provided with a removable cover plate or member 15. The arrangement of the casing is such that the air chamber and associated conduit may be made at a single die casting operation and thereby provide a valve casing which is simple in construction and more durable than similar devices now on the market.

The cover member 15 carries an adjustable tube member 17 which forms a communication to the interior of the valve chamber and the inner extremity of this tube forms a valve I seat 18 for an armature disc valve element 19 which is controlled by the pole pieces of the electro-magnet. Associated with the inner extremity of the cover 15 is a valve guide member 20. This member is in the form of a cage arranged to guide the lateral movement of the valve and retain the same relative to its valve seat whenever the cover is removed. The upper end of the guide is provided with a flanged opening so that the operation of the valve element will not be impaired and at the same time prevent the valve ele ment from being permanently removed from the valve seat should the cover be accidentally dropped by the workman when he is assembling or otherwise adjusting the valve parts.

While I have shown this valve retaining means as a flange, itis obvious that various other means may be employed at the top of the guide, such as overhanging clip or finger projections. To facilitate the passage of air' through the valve chamber the valve guide is perforated with openings 21 and some of these openings connect with slits 2222 to form resilient clips at the bottom of the guide to hold the same in place on the cover 15. In the. illustrated embodiment of my invention, the cover plate 15 is provided with a threadedportion 23'and a shoulder Qlwhich serves as a mounting forthe valve guide.

' vents'the disc from being accidentally lost or removed from the valve unit. This valve element is shown in Fig. 2.

The top portion of the valve casing, is provided with an opening 28] which is located between the pole pieces of the magnet and forms a communication between the valve chamber 14 and an 'opening 29in the wind box to which the valve may be attached. The relation of the air openings to the valve chamber is shown in Fig. 4. I 7

Having thus described a valve unit embodying my invention,'one of the important features isthe provision of a one-piece valve casing provided with a cover member which shall contain all of the movable valve parts sothat the same may be removed from and reinserted into the valve casing without removing the valve casing from its fixed support or otherwise changing the particular valve parts. By thus providing aremovable unit including the casing cover, valve guide and retaining means for the disc valve elefment which shall positively retain the element in operative relation toits valve seat, these parts may be quickly and readily adjusted prior to inserting them in the opera tive position in the valvecasing.

The opening at the top of the guide is adapted to receive the top portion 25 of the valve disc so that it shall engage the top wall and close the opening 28 when the disc is'actuated by the electro-magne When the valve parts are in operative relation, as shown in Fig. l, the guide 20 surrounds the disc valve so that when the cover is removed for any reason, the'flange 20 positively prevents the valve element from being accidentally displaced or lost. The valve element may be removed from its seat or otherwise disassem bled by unclamping the guide from the cover. In the illustrated embodiment of my invention this guide is frictionally clamped to the cover but it is obvious that it may be fixed to the cover by screw threads or equivalent securing means, if so desired.

While I have shown and described a preferred embodiment of my invention, it is obvious that various changes may be made therein without departing from thescope of the invention as set forth in the claims.
